' vantageously used for the evaporation of lyes.

In existing ,apparatus of this-type the liquid either passes through the .tubes which are -surrounded by the gas or vapor or the li uid i serve at the same time for is brought 'into contact with the outer sur ace of the tubes, while the heated gases pass therethrou h.

The sub]ect. of the present invention is a l device by means of which the pipes of an irrigating apparatus are at the same time irrigatedby liquids on the inside and outside and charged with gases` on the inside and outside and are thus used in two ways, so that the pipes of one and the same :pparatus can 'fferent purposes-for instance, evaporation, vaporization, condensation, absorption, ,and saturation.

panying drawings, wherein- Figure 1 shows a vertical section of the whole apparatus; Figs. 2 to 5, partial sections of various modifications thereof.

Similar letters refer to similar parts throughout the several views.

The apparatus, as shown in Fig. 1 ,consists of a shel orcasing a, divided, by means `of heads g and h, into three chambers or compartments b, c, and d. Secured in the heads g and h and passing through the compartp mento are pipes f, by which the compartments b and d communicate. Secured in the upper ends of the pipes f are small pipes 7c, open at their upper ends. l

The gases and vapors are conducted through the apparatus either in the direction of the arrow or in'the opposite direction, so that the collar m serves as the entrance to the distributing-chamber b, from which the gases and c, into the ascend, through the pipes y hr h h eave t oug t e upper space d, which they The apparatus is illustrated'on the accoinsocket o for further use, or otherwise the7yc7 ter through o into d and leave through and the collar m. The collar p serves to let the gases and vapois into the middle space c and collar g to let them out, or vice versa.

Collar 1' serves to let oif from the middle space c the liquid irri atin the pipes f on the outside, and the co ar s eads olf from the space b the irrigatin liquid which has irrigated the pipes f on t e inside. A

In Figs. 2 and 4 of the drawings I have shown transverse pipes Z, in the p i'esent instance crescent-shaped and provided with apertures in their up er sides for suppl g liquid for irrigating t e outer surfaces o the pipes f. It is evident that the liquid flowing out of the apertures in the pipes l will surround the outer sides of the vertical pipes f avity down this outer surface.

and flow by In Figs. 3 an 5 of the drawings I have shown an additional head i', in the c amber c intermediateof the heads y and h. The tubes f are firmly secured in thishead '1.,' but, as

shown, a helical passage is left between them through whichthe irrigating li uid may flow, so that the lower portions of t e pipes will be surrounded by a mantle of the liquid, as well as the upper portions. If, for instance,I

lyes are to-be evaporated which bear the con" -tact with gaseous products of combustion or l the like and if the above-described apparatus is used,l in which the 'pipesare irrigated on the inside and outside with lye and are charged on the inside and outside with waste` gases from fire places, the heating-surface is doubly utilized, and the evaporation is therefore twice as great. In both cases the. gases absorb vapor, the heat of Which they give off and make useful at another place. 'The -double irrigation also allows of evaporating on the outside of the pipes with an overpres- Sure and in the inside with a partial vacuum.

If hot air is used, the double uantitiesare saturated with vapor and are't ereby made in.' a high degree suitable for generator and water-gas heating. If the a paratus is to be used as a gas washer and a. sorber, it may Serve this purpose with the inner as well as Withthe'outer surfaces of the pipes, no matter whether ammonia gases or other vapors andgases are to Abe absorbed. In all these cases this apparatus, irrigated at the same time on the inside and outside and charged With gases or vapors, does double the Work of an ordina deserves t e name of double irrigator, which has been given to it.

What I claim as my invention, and desire to secure by United States Letters Patent,-

ratus of .a casing, pipes f With the pipes c and Z within said casing, means for admitting a liquid for irrigating said pipes f simultaneously on the inside and on the outside and for admitting gaseous fluids to said chamber around said pipes f and Withinsaid pipes f for the'purpose of producing evaporation, condensation or absor tion simultaneously on the inside and outsi e of said pipes f, substantially as set forth.

2. The combination in an irrigating apparatus of the pipes f With the pipes 7c and l, and means for distributing a liquid on the inte, rior and exterior surfaces of said pipes f, substantially. as set forth.

3. An apparatus of the class described l comprising a casing divided into a pluralit of compartments, tubes extending throug one of said compartments and communicating with the compartments adjacent thereto, means for distributing a liquid both on the interior and exterior surfaces of said tubes, and means for admitting a gaseous fluid simultaneously lto the interior of said tubes land to the compartment through which they pass.

'4. An apparatus of the class described comprising a casing divided into a plurality ofv compartments, tubes extending through one of said compartments and communicating with the com artments adjacent thereto, separate means fbr admitting a liquid and a gaseous' fluid to the compartment With which the upper ends of said tubes communicate, separate means for emitting such liquid and such gaseous iuid from the compartment with which the lower ends of the said tubes communicate, and means Within apparatus, for which reason it l the compartment through which the tubes extend for distributing liquid over the outer surfaces of said tubes.
